Shortlisted for ‘Sustainability’ and ‘Conservation & Regeneration’ Awards in Constructing Excellence in Yorkshire & Humber 2021 Awards

The original building comprised of three distinct sections, a barn, a two-storey dairy and a single storey milking parlour built at different stages over the 19th century. Construction is very traditional for this area of West Yorkshire and Peak District, 450 mm sandstone coursed rubble-filled walls with heavy stone slate roofs. The retrofit/conversion is being applied to the two-storey and single-storey buildings, while the barn is being left unimproved. The client brief was for a deep whole house retrofit and conversion similar to the previous Lower Royd project.
